Frequently asked questions
How much does a commercial RTU replacement cost?
5-ton: $9,500 – $16,000. 10-ton: $18,000 – $32,000. 20-ton: $38,000 – $65,000. Crane, curb adaptor, and electrical included.
Do you handle roof crane rigging?
Yes — we hold the required contractor licensing and coordinate the crane, spotters, and roof protection.
Can you convert an R-410A RTU to R-32?
No — refrigerants are not interchangeable. Full replacement is the path when the compressor fails on an R-410A unit past its useful life.
